PUMPING DEVICE FOR OIL-WELLS.

Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed June 21. 1907. Serial No. 380042.

To all whom it may concern:

Be it known that I, HENRY D. HAVEN, a citizen of the United States, residing at 5009 Washington avenue, in the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Pumping Devices for Oil-Wells, of which the following is a specification.

My invention relates to pumping apparatus for oil wells and has particular'reference to the construction and arrangements of the upper end of the casing and parts related thereto.

, The object of my invention is to improve the construction of the portion of the pum ing apparatus referred to, so as to adapt tl ie same for use with long stroke pumping mechanism, such as shown and described in a separate application filed by me, May, 4th, 1907, Serial No., 375,130. In said application I haveshown an oscillatory drum about which the operating cable is wound and at- I tach the other end of the cable to the polished rod by a suitable coupling. The length of stroke is measured by the amount of cable unwound and wound about the drum with each oscillation.

It is the usual practice to arrange the studing box at the top of the tubing, which is about three feet from the ground. Through this works the polished rod. The polished rod must be somewhat longer than the stroke of the pumping mechanism, hence, said mechanism must be arranged a considerable distance above the ground, especially when long stroke mechanism is used.

A particular object of my invention is to construct and arrange the tubing, stufiing box and related parts of the' umping apparatus, that the actuating mec anism may be round.

My invention will e more readily under-, stood by reference to the accompanying drawings forming a part-of this specification and in which,

Figure 1 is a sectional view of the upper end of an oil well, illustrating a pum ing apparatus embodying m invention. ig. 2 is a detail plan view 0 the fl e late attached to the upper end of the o tu e, 3 is a similar view of the flange late attac ed to the stufling box tube, and ig. 4 is a cross section upon an enlarged scale taken on the line, a:-a: of Fig. 1.

Referring to the drawing, 1 indicates the casing and 2 the casing head, within which is ,from which leads the oil pipe, 11.

arranged the casing ring, 3. The tubing depends from the casing rin 3 and is of but sli htly smaller diameter than the casing for a istance approximately the same or a little 1 and the tubing, 5 and 7 and is carried oil by a pi e, 8, leading from the casing head.

9 in( icates a tee arranged above and connected to the tubing, 5 by a nipple, 10, and A nipple, 12, is arranged at the u per end of the tee, and to this is attached a ange pl ate, 1.3, having a plurality of holes, 114,11: purpose of which will appear hereinafter.

Arranged concentrically within the part, 5, of the oil tubing, is a tube, 15, which reaches nearly to the nipple, 6. The tube, 15, is supported by a flange plate, 16, which rests upon the flange plate, 13, and closes the top of the oil tubin The flange plate, 16, is provided with a plurality of holes, 17, and bolts, 18 passing through the holes, 14 and 17 hold the plates, 13 and 16 securely together, and a ackin ring, 19 com letes a tight joint.

pon t e lower end of the tube 15 is arranged the stufling box, through which passes the I need not be removed from the well for this purpose, I have recourse to the following novel. arra ement. Upon the lower member, 22, of t e stufling box, I provide lugs, or ears, 24, and upon the inner face of the tube, 5, sli htly above the nipple fi, I provide vertical y disposed ribs, 25. To tighten the stufling box the bolts, 18, are removed, after which the flange plate, 16 and the tube, 15, are turned, the flange fplate being provided with wrench holes 26 or this purpose. As the tube 15 is turned, the part 21, of the stufling ox is turned also. However, the lower portion 22 is'prevented from turning by thel 24 and ribs 25. I

.It seen byreference to Fig. 1' that the ribs, 25 are uite long in comparison with the lugs, 24. '1 ese are formed this Way so that tie stulling box tube, 15, may vary a little in length without interfering with the operation of the device.

The stufling box tube, 15,-is made substantially the length of the polished rod, 20, and it is evident that it ma be made of any length for pumping mechanism of any stroke. The upper end of the polished rod is attached to the cable, 27, by a cable socket, 28, and the cable is connected to the pumping mechanism which may be of a rotatory, oscillatory or reciprocatory type. As the upper end of the rod, 20, need not rise above the flange plates, it is evident that the operating mechanism may be placed close to the ground, especially if this is the drum mentioned in the aforesaid prior application.

Having described my invention, what I claim as new and desire to secure by Letters Patent is,

v 1. In a device of the class described, the casin and easing head, in combination with the oi tubing depending from said head, and having an enlarged upper end, a tube of smaller diameter than said enlarged end and depending concentrically therein, and a stufi ing box arranged at the lower end of said tu )e, substantially as described. I

2..In a device of the class described, the casing and'casing head, in combination with the oil tubing, depending from said head within said casingand having an enlarged upper end, a tee connected to said tubing above said casing head, and a flange plate arranged above said tee, a tube of smaller diameter than said enlarged end, and depend ing concentrically therein, a flange plate secured to the upper end of said tube, and resting upon the aforementioned flange I and one plate, and closingthe top of said oil tube, and a stufling box arran ed at the lower end of said tube, substantialIy as described.

3. In a device of the class described, a casing and easing head, in combination with the oil tubing depending from said head, said oil tube comprising an upper section of slightly less diameter than said casing, and a re duced lower portion, a tee arranged at the upper end of said enlarged portion above said casing head, and a flange plate, securedto the upper end thereof, a tube of smaller diameter than the enlarged portion of said tubing and depending concentrically therein, a two part stufling box, arranged at the lower end of said tube, means for turning said tube orti'on of said stuffing box, and means for olding the other part of said stufling box against rotation, substantially as and for the purpose described.

4. In a device of the class described, a casing and casing head, in combination with the oil tubing depending from said head, and having an enlarged upper end, a stufling box tube of smaller diameter than said enlarged end, and depending concentrically therein, a stufling box arranged at the lower end of said tube, a long stroke polished rod extending through said stufling box, and an operat-. ing cable connected to the up er end of said rod, said stuffing box tube eing substantially the same, or of slightly greater length than said rod, substantially as described.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
